Embodiment Construction

[0014] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0015] Such as figure 1 As shown in 2, a limit device for controlling the irradiation range includes a radiation source 1 for generating radiation. A limit device 2 for controlling the irradiation range is provided on the ray transmission path. The limit device is driven by a motor Drive; The limit device 2 is a cylinder, the end of the cylinder 2 is installed with a movable cover sheet 3, the limit device 2 is a cylinder, the end of the cylinder is installed A replaceable cover sheet 2 is provided with an opening 4 that allows rays to pass through, and the opening 4 is polygonal, circular or elliptical. The limiting device 2 is made of a material with low ray transmittance.

[0016] The embodiments of the present invention are only used to illustrate the present invention, and do not constitute a limitation to the scope of the claims. Other s...

Abstract

The present invention discloses a stop block which controls irradiation range and is characterized by comprising a radioactive source used for generating ray; the stop block which controls the irradiation range is arranged on a ray transmission path; and the stop block is driven by a motor. The stop block has the beneficial effects of simple structure, simple operation, being convenient for changing irradiation range and improving the ray treatment effect.

Description

Technical field [0001] The invention relates to a limit device for controlling the irradiation range. Background technique [0002] At present, tumor diseases are one of the main diseases that plague mankind. In particular, cancer has become the leading cause of death. In the prior art, the main method of treating cancer is chemotherapy and drug comprehensive treatment. The chemotherapy equipment in the prior art often has a complicated structure and difficult movement due to too many parts. During treatment, the patient can only change the position. [0003] The distribution area of ​​tumor cells is often irregular. When radiation treatment is used, only the tumor site needs to be irradiated. For normal cells, there is no need to irradiate. Therefore, it is very necessary to provide a limiting device that can change the irradiation range. Summary of the invention [0004] The purpose of the present invention is mainly to solve the deficiencies in the prior art and provide a lim...
